GENERAL PUMP INSTALLATION / SETUP (FIG 1)
City booster pump installation is shown per
FIG 1. During pump use, insure ball valves #1 and
#2 are open, and ball valve #3 is closed.
#1 An Adjustable Pressure
Regulator (APR#1) is required on the suction side of
the pump (see fig 1) if the incoming water pressure
can exceed the maximum input pressure.
#2 An Adjustable Pressure
Regulator (APR#2) is required on the Discharge
(See fig 1) to insure maximum water pressure does
not exceed local plumbing codes.
#3 A Pressure Relief Valve (PRV)
connected to a drain is required (see fig 1) to safe
guard plumbing from exceeding max pressures if the
Pressure Regulators fail. Typically the PRV would
be set 5 psi higher than the APR#2.
NOTE: Optional external water tank can be used to
decrease the on/off cycle rate of the pump system,
which can extend the life of the pump. (Typical tank
3 gallon draw down.) Set tank PSI equal to pump
tank PSI.
The entire system must be air and
water tight to maintain prime. Use thread tape on
all connections to insure no leaks. Hand tighten
all threads and then add additional half turn with
wrench.
